LVPECL differential signaling keeps the edge jitter low over long board traces, so the clock distribution tree doesn't degrade the timing margin at the FPGA or PHY input. The 2.25V to 3.6V supply range means the same BOM position works on a 2.5V FPGA bank or a 3.3V PHY rail — no extra LDO, no voltage divider. Housed in a 6-SMD, No Lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm — this is the standard 5×3.2 mm oscillator footprint, pin-compatible with quartz-based XOs of the same size. Microchip's MEMS fab capacity is independent of the crystal supply chain.","metaTitle":"DSC1122BI2-148.5000T 148.5 MHz LVPECL MEMS Oscillator","metaDescription":"DSC1122BI2-148.5000T: 148.5 MHz LVPECL output, ±25 ppm stability, -40°C to 85°C, 2.25V-3.6V supply, 6-SMD package.
